How does a MasterCard Credit Card Transaction work

There are three main steps to how a Mastercard transaction works

  1. Authorisation
  2. Clearing
  3. Settlement

Authorisation

A MasterCard is authorised at the time of purchase and follows these 7 steps.

  1. The MasterCard credit card containing the account information is provided to the merchant from the cardholder.
  2. The cardholder's bank is determined by MasterCard at the request of the merchant's Bank.
  3. The MasterCard credit card security features are checked by the MasterCard authorisation system and sent for approval to the cardholder's bank.
  4. The purchase is approved by the cardholder's bank.
  5. This approval is sent by MasterCard to the merchant's Bank.
  6. Approval is sent to the merchant from the merchant's bank.
  7. Cardholder receives a receipt after he completes the credit card transaction.

Clearing

Clearing is usually accomplished within one day and follows these 3 steps.

  1. The MasterCard network receives the purchase information sent to them from the merchant's bank.
  2. The information is validated by the MasterCard clearing system, which then sends this purchase information over to the cardholder's bank.
  3. Data is then prepared for the cardholder's statement.
    Comprehensive reconciliation is provided by the MasterCard clearing system to both the cardholder's bank and the merchant's bank.

Settlement

Settlement of the purchase usually occurs within 2 days, in this order.

  1. Payment is sent by the cardholder's bank to the MasterCard counter-party to settlement.
  2. Payment is sent over to the merchant's bank from the MasterCard counter-party to settlement.
  3. Merchant is paid by the merchant's bank for the cardholder's credit card transaction.
  4. The cardholder is billed by the cardholder's bank.

As you can see, this is quite a process, and as a MasterCard client it is good to know everything you can about your card. It can help you understand how a mistake can possibly be made, and how your statement gets processed.
